Control device for driving on the road
The driving control device consists of one micro-switch (Fig. 5.9, 1) found behind the telescopic
boom and a micro-switch found on each stabilising beam (Fig. 5.8, 2). These micro-switches work
simultaneously and, when they are all activated, the ‘go’ indicator on the cab panel lights up and the
platform is entirely closed, reach to be driven on the road.

Working area control device
The working control device consists of one micro-switch (Fig. 5.9, 1) found on the side of the telescopic
boom near the boom rest, one micro-switch (Fig. 5.8, 2) found on each front stabiliser beam, and two
potentiometers (Fig. 5.8, 3) found on the slewing ring.
The micro-switches mentioned above work simultaneously with the potentiometers to monitor the
movements of the elevating work platform, adjusting the extension of the telescopic boom and thus
the work area.
